United Airlines said Tuesday it was replacing the hefty flight manuals and chart books its pilots have long used with 11,000 iPads carrying the same data.

The 1.5 pound (0.7 kilogram) iPad will take the place of about 38 pounds (17 kilograms) of paper instructions, data and charts pilots have long used to help guide them, parent company United Continental Holdings said.

The popular tablet computer will carry the Mobile FliteDeck software app from Jeppesen, a Boeing subsidiary which provides navigation tools for air, sea and land.

"The paperless flight deck represents the next generation of flying," said Captain Fred Abbott, United's senior vice president of flight operations.

"The introduction of iPads ensures our pilots have essential and real-time information at their fingertips at all times throughout the flight."

It will be supplied to all pilots on United and Continental flights; the two carriers merged in 2010.
